Expertise and Services:

Physicist, Frequency Standards, Metrology, Spectral Purity Expert Consultant Resume

This expert has experience in specification, design, development, and measurement of a wide range of analog circuits with very low phase modulation (PM) and amplitude modulation (AM) noise from audio to 100 GHz.

Specialization of this expert includes crystal oscillators and systems, microwave sources and systems, distribution systems, analog divider systems, and calibration systems. Other specialties of this expert include frequency synthesis systems, very stable thermal control systems, and mitigation of environmental effects in frequency references.

This expert is highly experienced in areas including the analysis of residual PM and AM noise of a system and discerning the origin of excess noise for carrier frequencies from audio to 100 GHz. Other areas of knowledge this expert has are computing phase and timing jitter from measurements of PM noise. This consultant is also skilled in designing measurement systems with in-situ calibration to achieve rapid throughput for AM and PM measurements, measuring and understanding the residual PM and AM noise in components, and troubleshooting ground-loop problems in frequency standards and measurement systems.


Professional Experience:

Consultant, Kevin Kennedy Associates Inc.

Providing expertise in physics, frequency standards and metrology, electronic systems spectral purity, research science, inventing, and related expertise to a wide variety of clients.

 

Chief Scientist, quartz crystals and precision oscillator supplier

Was consultant involved in the development of ultra-stable clocks, crystal-controlled oscillators with improved short- and long-term stability, low-noise microwave oscillators, frequency synthesis from RF to 100 GHz, low-noise distribution systems, low-noise frequency stability measurement systems, and accurate phase and amplitude noise metrology from dc to 100 GHz.

 

Leader, Phase Noise Group of the Time and Frequency Division of the National Institute of Standards and Technology, formerly the National Bureau of Standards

Was engaged in research and development of ultra-stable clocks, crystal-controlled oscillators with improved short- and long-term stability, low-noise microwave oscillators, frequency synthesis from RF to infrared, low-noise frequency stability measurement systems, accurate phase and amplitude noise metrology, and ultra-high stability ovens.

 

Postdoctoral Fellow, Joint Institute for Laboratory Astrophysics, Boulder, CO

Focused on developing low noise techniques for long-term storage and nondestructive detection of fragile atomic ions stored in Penning traps for low energy collision studies.

 

Graduate student, under Dr. Hans Dehmelt (1989 Nobel Prize physics), University of Washington

Ph.D. thesis required the development of very low-noise electronics and the development of long-term storage and nondestructive detection techniques of electrons stored in a Penning trap. This work resulted in the first measurements of the anomalous magnetic (g-2) moment of low energy electrons and was one of the first low energy tests of QED.
